Decide the percentage of profit you’d like to earn. In the United States, a business has only a few years to show no profit before they are considered a failed endeavor. So it's a good idea to put some extra money into your rate to show a profit. I don't recommend aiming for a lower profit than 10% - I like to aim for 20% profit.

Multiply your overhead rate times 20% and add that to your overhead rate

This is your Hourly Rate

Round up or down to get a number that sounds friendlier like $150 or $185 per hour.
